Tin snips/sheet metal shears. Also, you absolutely need to prime & seal the holes you drill into the car (if you didn't do that already) so that they won't rust. Even in a dry/dry-ish climate there will be moisture at some point and it will invade those unprotected holes. Rust Never Sleeps. Your heat shield looks great by the way!
i was thinking of taking a level on a 2x4 across the fender surface where the hood meets it but this would be more exact. but i guess the foam would take care of minor miscalculations
man that came out looking really freaking good. I remember on my first car back in high school I decided to make my own intake heat shield out of cardboard wrapped in aluminum foil lmao. Needless to say yours looks (and probably functions) 100 times better than mine did
I have to say this was one the best videos I've seen for DIY stuff...Definitely worth the 16 minutes!!!!!!!!!!!!!!! And great idea with using the blue tape to see where it stuck to the hood!!! Doesn't it just feel great to do your own custom work even if it takes some time?!!!!! KUDOS MY MAN!!!!! :) ;)
Nicely done i did something but i use bookshelf hangers they vome n 3 different sizes but i like the gas hose trim i wasn't for sure what i was going to used on the edges so tks for content
Very nice video! Maybe the best one I found. But where is the air coming from? because the filter is now almost boxed / closed when closing the hood. Kind regards, Xander
Very well done my friend. Now get u some medical grade water activated fiberglass ina roll and make it from composite! I’m doing an intake now for a bmw 328i and and all in I’m at $60 or bucks. Not bad compared to $400!
Thanks! Ya that was a concern I had too! Some air comes thru from near the upper right side of the radiator (facing the car).. there is also a hole under the headlight housing, pulling air from the front of the wheel well/bumper area.. I just recently fab'd up a vent hose to take air from the front bumper inlet and direct it thru that hole.. It seems to work well
The sad part is, after all that dedicated work, it's been proven the dyno'd HP and TQ difference with CAI's is not even substantial enough. It may definitely "sound" better but the stock airbox with a K&N FILTER is thee fastest and most cost effective improvement.
k&n filters are trash, not only does the oil from them get sucked into the sensors and throttle body but their filtering efficiency is laughably bad compared to a standard oem paper filter.
@@ryanfrizz - K&N filters or dry BC filters, whatever you like John, either way go online or watch a few UA-cam videos, you will see dyno runs showing CAI kits making very little improvement at all compared to stock air boxes with aftermarket filters
Thanks for the input!! You are correct sir! I'm sorry if you were looking for info on making large HP gains :/ (try searching "forced induction") However, after all my dedicated work, I did happen to learn something about basic fabrication and I managed to keep some hot air out of my current intake setup. Personally, that's a win-win!
@@_GarageThings - AMEN brother! Huge respect for taking on the task of fabricating and building something from scratch you can call your own! Those are projects and experiences you will always learn from! Keep up the hard work and the motivation - definitely a win-win!
Well done. Definitely enjoyed the whole process. Will make something like this also, but with a top cover (rain cover) coz my hood has vents. Keep up the great work 💪🍻
Wow it looks fantastic. Definitely going to be making one of these for my speed3 soon. Just can't justify spending the money on the corksport one if I can just make one myself that works just as well.
Hey thank you! Ya I honestly could have done better with my measurements (especially between the shield and hood).. Spending extra time measuring will definitely show in the end.. Good luck!!
Great im planning to do one to upgrade. The intake from my 2011 chevy Colorado right now makin the design to improve the one that sells k&n didn't found one from another brand. Thanx Saludos desde Ensenada México 🍀🎶🍻😉
Where did u get the flexible rubber protection on the upper lip ?? Thanx Uuh sorry i missed that part now i know! If any one knows the correct rubber band that goes on the upper edge let me know please! N i will share my design with u. Blessings!
I want to get a cold air intake for my '96 corolla but want a heat shield so the heat from the engine doesn't stick to the filter (obviously) but the way the factory air box is designed looks kinda strange, it has a hole on the bottom (under the factory drop in filter) but it leads to something & idk what it does exactly would I need to remove it if I ever make a DIY heat shield for the cold air intake? it uses clips to the hold the whole air box down
Usually the hole under the factory air box will have a plastic tube attached, directing air to the intake.. Sometimes, these are removed and misplaced.. That could possibly be what happened to yours I couldn't tell you exactly without seeing it.. But I imagine, you should remove all the airbox components if you are replacing it with a aftermarket intake system..
@@_GarageThings it still has that tube just don't know I would mount one without it hanging kinda loose cause it sits a little higher above the transmission
Good options for intake systems are the cts and k&n intakes they range from $250-$280 but honestly pick up a spectre intake from Autozone and slap it on to your oe maf hose/intake hose you’ll get all the sounds that the expensive systems give you minus the heat shield then you can just follow this video for the shield good luck!
Great question! Prior to making this, I hadn't even checked to see if K&N made a plug-and-play option for my Miata. I just wanted to make something haha But I should have included build costs in the video. Here's a rough breakdown of the materials as I remember: Vent Pipe - $15 (home depot) Stick-on Heat Wrap - $18 (amazon) Aluminum brackets and Hose - $5 (home depot) Paint - $0 (already had it) Total for materials = $38 I already had all the tools aside from the Rivet tool ($5) and Rivnut tool ($25, both from harbor frieght), which I see as somewhat of an investment since I get to use these in the future. After a bit of searching, it appears that K&N does not make a heat shield for my application. But I did see comparable heat shields for other intake brands are around the $100 range. Would I recommend building over buying? It depends.. If you want to save a few bucks and you have the tools, confidence and will to build it, then go for it!! Or, you can spend a little extra and buy it.. But I should add, it is VERY satisfying seeing something I built every time I pop the hood :)
so I have the short ram intake (aka hot air intake) & besides thin sheet metal, what other stuff would I need to start making a heat shielf? (yes I'm aware I'll also need high temp paint & a heat barrier)
If my engine is pretty far from my air filter do i still need the heat shield? My car is a Seat Leon 1M 1.9 TDi 150 hp it this is going to help if you want to see their positions under the hood. Sorry for my bad english
I'm not familiar with that application.. Generally, if your air filter is in a location that gets heat from another area, it would help to create a barrier to stop some of that heat.. I suggest checking the forums and asking other ppl with the same car.. Hope this helps!

My intentions weren’t to make HP gains.. the goal was to create a barrier between the hottest area in the engine bay (exhaust manifold) and the intake filter in hopes to draw in less hot air and essentially not lose HP from the heat There is an opening allowing cooler air from in front of the filter to the main bumper inlet, so that helps too According to the butt-dyno, there’s a noticeable difference, especially on hot days and long drives. It seems that the car isn’t being “choked” with hot air, if that makes sense Hope this helps!
@@_GarageThings nice seems legit. I thought there was no hole for ambiente air to come in. Ima do something similar to my car ive been seeing a lot of positive feed back and ita cheaper amd better than a cai
And I couldn't be happier! I've also, upgraded my suspension - in essence, removing my factory suspension (with struts and springs) and replacing it with aftermarket suspension (with struts and springs) But good news for some people - you don't have to upgrade or modify your car if you don't want to!
@@Siriusgxmiq yes, it is,lol. It's an enclosed box,made from a thermal resistant plastic, placed in an area that gets colder air from the front of the car; that IS a Factory CAI system. Car companies use these guys called "engineers", who make these things, lol.
@@hotrodray6802 that pile he's using is actually a heat sink, being so long and right next to the engine all along it's run. These guys think making more noise makes more power...sheesh.
Air comes in from an opening at the front where the radiator is.. also an opening under the front headlight where I routed a 3" flex hose from the bumper air dam.. This forces cool air into that space.. It actually makes a big difference! I've been meaning to do a video on that
It's a fuel hose which is fairly heavy-duty rubber.. Most any plastic or rubber would be ok [in the engine bay] as long it's not touching the exhaust manifold or anything else that could melt it
Love a good old bit of CAD: Cardboard Aided Design! :D
As for the rubber, door weather stripping for cars work great
Great idea and use of resources. Great payback for the cost involved and tremendous for DIY car people. Thank you!

Mike D Hey thanks for the tips! Didn’t even think of that.. I’ll have to go back and seal those holes 👍
Now THAT'S a how to do it DYI vid!! Excellent amount of detail, thanx 4 not skimping on any info 👍🏻
Pro tip, you can use blutack or play-doh for clearance checking as well. Stuff the putty on it and then close the bonnet :)
Genius!! Thank you!!
i was thinking of taking a level on a 2x4 across the fender surface where the hood meets it but this would be more exact. but i guess the foam would take care of minor miscalculations
I’ve always enjoyed making things work on my own. Totally appreciate your effort. Thanks for keeping it clean, God bless you
I am very impressed with how this turned out, definitely feeling inspired
Dope video. Love the creativity the car community brings.

@@_GarageThings More than welcome!!!
Im gonna be modding my CAI intake by swaoping out the filter with a 6 in velocity stack and i need a heat shield thanks for the tips
In my opinion it's best to have a big airtight airbox directly routed to the front of the road, but I must say it's nice build man,good job !
good ideas and done with general shop tools!!! ima give this way a shot thanks!
Good job! Really 👍👍👍
the only thing I would have added would have been a BOA that forces fresh air in from the bumper or grille.
That tape high-spot trick was SWEEEEEET! Great job man this was awesome, definitely going to be my weekend project now.
Great job, those pop nuts are brilliant! Cheers mate!!
GOOD TIMING. 👍👍2 hrs ago I was sitting here planning my custom CAI.
with patience comes success .great job!!!
Fantastic! This gave me some great ideas💡👍
You sir, have earned your PhD in garage engineering!
New Sub too
When the hood get close , there's a hot air also sunction by the air filter
Nicely done i did something but i use bookshelf hangers they vome n 3 different sizes but i like the gas hose trim i wasn't for sure what i was going to used on the edges so tks for content
Good job bro. I'm already make heat shield with fiberglass. Now just put CAI for it. That makes it better.
Thanks man, it's gone a be my next project. Because of you now know i know the right way to do it my own custom p-flow box.
Vehicles already have a cold air intake from the factory, and it's not restrictive at all.
@@manny6584 that’s correct 👍
Great video. I need to make a heat shield myself, but unfortunately patience and finesse aren't my strong points. Definitely looks doable though.

You could also wrap the intake pipe in silver tape.

Great video so much cheaper then buying a heat shield
love the thumbnail 😂😂

What type of material is good for the airbox. Would be better for it to not be easily melted and also not be extremely hot when at long drives
Wow looks awesome man, well done!
Nice video about to do something similar on my car.
Great job, be careful that is earthed to the car now . Make sure it doesn't give you problems.

most of the shields that ive seen suck a LOT of engine air.

after and before temperature check????????????????????????????????????????????????
